I have a data sheet of four columns.
The first two columns are used in an array on my summary sheet. Column A contains the column headings, column B contains the row headings of this array.
I need to use some form of COUNTIF or SUMPRODUCT to count the unique entries in column C for each combination of Column A & B on the data sheet.
So far on my summary sheet I have
=SUMPRODUCT((Data!A3:A20000=B3)*(Data!B3:B20000=A4),(Data!D3:D20000))
Which seems to return 0 and wouldn't account for unique references only anyway.
Does this make sense to anyone & can you help?
Thanks.
